hello, i own a 91 DA and im haveing problems with it, one day i was driving along and it started missing, so i got home and let it run for about 5 minutes, it only got worse as it was sitting there so i turned it off and pulled the plugs. it seemed that the #2 cyl plug had been fouled out, so i replaced them all and started it back up, it ran fine for about 5 minutes then started to miss again. so it sat for about 2 weeks intill i got a used dizzy off of ebay for a reasonable price, installed the dizzy, started it back up and it ran fine, then i drive it for about 10 minutes and it starts to miss again and led to fouling of the #2 cyl plug, checked my compression and its not the best but is still at a decent level, got the ole timeing light out and started the teg back up, tested all cyls and all but #2 were fireing fine. so, my question for you is. do i have another bad dizzy or is it something els? if it is something els, what could it be? thanks for the help guys.
also, i got new wires when i got the dizzy...

I don't think a bad dizzy would just foul #2 cyl. Maybe a bad dizzy cap or ign wires. Anyway you probly did all that. Try swapping #2 & 4 fuel injectors see if the problem follows the injector.
